Datatype selection option for roofline (#624)

Added command line option to specify which datatype(s) to capture into the roofline PDF(s).
All datatypes are still collected by roofline call if applicable, but only specific datatypes are plotted into PDF outputs. Will dump out all datatypes into one graph, but separate FP from Int into two graphs if needed. Will skip datatype and give error message if the datatype is not valid on a particular gpu arch.
Default is FP32

Reworked roofline calls and plotting to be general enough such that any new datatypes added into rocm-amdgpu-bench can easily be reflected in rocprof-compute with simple modifications in roofline_calc.py.

Adjusted ctest to reflect expected default pdf outputs from roofline.

+   ROCm Compute Profiler currently captures roofline profiling for all data types, but has the ability to reduce clutter in the PDF outputs by selecting datatype(s). Selecting multiple datatypes will overlay the results into the same PDF. If the user would like separate PDFs for each datatype off of the same workload run, the user can run the profiling command again with the single datatype as long as the roofline.csv still exists in the workload folder.
